SPECIFICATION forming part of Letters PatentNO. 657,507, `dated. September 11, 1900.

l `Application led .Tuly 9, 1900. "Serial No. 23,039. (No model.) i

. To all, whom, t may concern:

a nut, so that the free end of the ratchet may properly engage with a bolt,`to effectively lock the nut against Aaccidental lturning thereon and to permit of the convenient removal of the nut.

With this and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompan yin gdrawings, and particularly point- A ed ont in the appended claims, it beingun-` derstood that changes in the form, proportion,

size, and minor details may be made within' the scope ofthe claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is a perspective view of a bolt and nut having a spring ratchet device applied to the latter in accordance with the present invention. Fig. 2 is a front elevation of the bolt and nut. Fig. 3 is an edge elevation of the nut. Fig. 4 is an elevation of the inner face of the nut. Fig. 5 is a transverse sectional view taken on the line 5 5 of Fig. 41 Fig. 6 is a transverse sectional view taken on the line 6 6 of Fig. 4.

Corresponding parts are designated by like charactersof reference in all of the figures of the drawings.

Referring to the accompanying drawings,

face of the 'nut and intersects the adjacent Be it known that l, SAMUELCLAIBORNE` BAUGHN, Jr., a citizen of the United States,v residing at Comer, in 'the county of McLean l and State of Kentucky, have invented a newV inner end of the groove 1.

The ratchet device consists in asubstantially L-shaped stimetalspring 6, which has one arm or branch received within the slot or groove't, so 'that the other branch 8 is disposed substantially parallel across the outer face of the nut, with its free extremity bowed, so as to engage with the grooves of the bolt. This ratchetdevice is formed from a iiat piece of spring metal, with the attaching branch 7 com parati vely broad to give strength to the device and the other branch being Ysomewhat narrower and bowedto give the required spring action and to bring the free extremity thereof into position for engagement with the grooves of the bolt. The rear extremity of the attaching branch 7 is bent at substantially right angles thereto, as at 9, so as to lie in the groove 5 in the back of the nut and snugly iit said groove, the opposite edges of which are upset, as best indicated at 10 inFg. 6 of the drawings, so as to overhang and bind upon the portion 9, and thereby xedly connect the rear end of the ratchet device to the nut. As indicated in Fig. 3,

`the narrowest portion of the groove 4, which is at the rear end thereof, snugly receives the adjacent portion of the attaching branch, while the remaining portion of the latter is free from the opposite'walls of the groove, and thereby may` move laterally within the groove, so as to render the spring arm or branch more elastic than if the attaching branch were entirely rigid.

From the foregoing description it will be seen that the present invention provides an exceedingly simple and efficient manner of attaching the ratchet device to the nut without employing separate fastenings, which are liable to become loose. Also the ratchet is flush with the-inner face of the nut, and also with the marginal edge thereof, so that it does not present any projections to interfere with the turning of the nut, and the latter maybe set up Hush against lthe object to which it may be applied. The spring branch or tongue, which travels across the ratchetgrooves in the bolt, is located entirely upon the outer face of the nutso'as to'be in position for conveniently disengaging the free IOO end thereof `from the'grooves ofv the bolt ifo -permit of theremoval lof the' nut. v 4 l), l Y
